Question

At time , a 2450 rocket in outer space fires an engine that exerts
an increasing force on it in the -direction. This force obeys the equation
, where
1.55 is time, and has a magnitude of 781.25 when = 1.55.

A. Find the SI value of the constant .

B. What impulse does the engine exert on the rocket during the
1.50 interval starting 2.00 after the engine is fired?

C. By how much does the rocket's velocity change during this
interval?
